Wireless systems have been developed to monitor bridge loads and to help determine the remaining service life of bridges. This article describes three wireless bridge monitoring systems that gather data from analog sensors attached to bridge members. The systems range in price from $1,000 to $30,000 per computer node. Data gathered is processed and sent to an on-site central controller, where the data is analyzed or accessed via a modem hook up. These systems are beneficial in two ways: they provide data on dangerous conditions that might be missed on visual inspection and they are quick and easy to install, cutting labor time by more than half. The systems have been tested and proved viable on actual bridges.
